* bugfix: destructor for base class RIFF::Chunk accessed members of
derived class RIFF::File, which is bad, and caused crashes when
using Visual C++
* bugfix: EG3 depth parameter was not saved correctly
* fixes for building with Visual C++

* bugfix: refuse RIFF::Chunk::Read() in case chunk has just been added,
that is not written physically yet (#82)
* bugfix in gig::Sample::LoadSampleData*(): reset sample read position
to sample start before trying to (re)load sample data from file (#82)

* bugfix: saving to the same file after the file size had been
increased made the file corrupt (#82)
* bugfix: removed another iterator invalidation in DeleteSample
* changed the functions for midi rules, to get rid of the iterator

* src/gig.cpp, src/gig.h:
added File::SetAutoLoad() and File::GetAutoLoad() for allowing
applications to retrieve very superficial informations like amount of
instruments and their names in a very fast way

* added virtual method SetKeyRange() to the gig and DLS Region classes,
which automatically take care that the "resized" Region is at the
correct position and that the lookup table for
gig::Instrument::GetRegion() is updated (moved code from gigedit)
* MoveRegion() method of DLS::Region class is now private
* bugfix: gig::Instrument::UpdateRegionKeyTable() did not reset unused
areas

* AddDimension now copies all parameters from existing dimension
regions and also makes sure that the samplechannel dimension is
placed first
* Windows fixes: compile error in DLSID generator, saving a new file
didn't work

* write support fixes: allow regions/dimension regions without mapped
samples, 3gnl in v3 files now always has 128 entries, several
parameters where incorrectly saved due to an operator precedence
mistake
* DeleteSample now removes all references to the deleted sample

* added write support for 24 bit samples
* set default version to 3 when creating a new file
* more chunk order fixes
* 3ewg is now bigger in v3
* one more einf field figured out
* added some dimension strings to gigdump

* more write support fixes: crossfade parameters were not saved, v3
dimension limits were not correctly initialized and saved when
dimensions were added or deleted, v3 wave pool offsets were not
saved correctly

* fixed exceptions which occured when trying to save a new instrument:
- override the gig::Regions sample reference simply by the region's
first dimension region's sample
- fixed software info field which was wrongly stored on instruments

* added new method File::DeleteGroupOnly() which only deletes the given
group but moves all its members to another group, the other method,
that is File::DeleteGroup() now removes not just the group, but also
all the samples that belong to that group

* src/gig.cpp, src/gig.h: fixed behavior regarding the newly added support
for sample groups, the initial implementation assumed a group index of 0
in the .gig file to mean "no group assigned" and thus the possibility
that there might not be a group at all, but in fact the .gig format
assumes always at least one group (the default group), thus a group index
of 0 means "member of default group"

* added functions libraryName() and libraryVersion() to each of the three
library units (RIFF,DLS,gig)
* all tools now offer a command line switch -v to show the tools revision
and the used libgig version
* man pages are now auto generated with the correct libgig version

* src/gig.h, src/gig.cpp: implemented progress indicator callback mechanism
for loading instruments and samples
* src/DLS.cpp: fixed File constructor which caused variable
File::Instruments always to be zero
* src/RIFF.cpp: fixed method List::LoadSubChunks() which did not restore
the original position within the body of the given list chunk

* gig::Sample: external decompression buffers can now be used for streaming
with Read() and ReadAndLoop() to avoid race conditions in case of
multiple streaming threads
* fixed some memory leaks caused by non virtual base constructors

* src/gig.cpp, src/gig.h, src/gigextract.cpp: Support for compressed
mono samples. Experimental support for compressed 24 bit
samples. Fixes for decompression on big-endian CPUs. Fix for bug
that truncated end of compressed samples.

* src/gig.cpp, src/gig.h: added method GetVelocityAttenuation() to class
DimensionRegion which takes the MIDI key velocity value as an argument
and returns the appropriate volume factor (0.0-1.0) for the sample to be
be played back, the velocity curve transformation functions used for this
are only an approximation so far

* src/gig.cpp: fixed bug in decompression algorithm which caused it not to
detect the end of a stream
* various endian corrections (successfully tested now on ppc)
* minor adjustments to avoid compile errors on some systems
(using now pow() instead of powl() and --pedantic g++ compiler switch)
* src/RIFF.cpp, src/RIFF.h: added additional API documentation
